The evolution of East Tennessee Mechanical Contractors, Inc. (ETMC) from a construction specialty firm to a premier facilities and construction management company is a formula for success. ETMC use the same elements of this formula to successfully complete each project.

The company was founded in 1978 by the late Don E. Deathridge, Sr. Don targeted growth opportunities within the City of Knoxville, Oak Ridge and the Tennessee Valley Authority (TVA) and Department of Energy (DOE) communities. Don's brother, Mark Deathridge, joined the company a year later as Vice President and Chief Executive Officer (CEO) and handled the administration and marketing of the business. Together, Don and Mark plotted a strategic path of industrial and economic growth for ETMC. They successfully participated in the U.S. Small Business Administration 8(a) contracting program.

As President and CEO, Mark Deathridge has guided the company through 8(a) graduation and the continued re-engineering of ETMC operations and management processes. ETMC has served as prime contractor for industry leaders such as U.S. Department of Energy Oak Ridge Operations (US DOE), B&W Y-12, LLC, Oak Ridge National Laboratory (ORNL), Veterans' Administration, Brasfield & Gorrie, LLC, Skanska, Tennessee Valley Authority, McGhee Tyson Airport, Tennessee Department of Transporation, Rentenbach, Nissan Corporation, Blue Cross / Blue Shield, the Great Smoky Mountains National Park, Knoxville Utilities Board (KUB), Knoxville Community Development Corporation (KCDC), and many others.
